Commercial Landscape Contractors in Toronto and Central Ontario

About Us

At Cornerstone Ltd, our reputation of excellence has evolved from our true passion for the industry and our dedication to provide quality guaranteed services.

Since 1986, we have provided professional landscape construction and landscape management services to thousands of clients across the GTA and Central Ontario.

Today, the Cornerstone team is committed to excellence and client satisfaction thus has grown into a diversified organization offering many services relating to green space management.

Included in this, is to respect our environment. We use state-of-the-art low emission equipment to minimize our carbon foot print, and by utilizing GPS tracking, we are able to plot efficient travel routes in order to reduce fuel consumption, monitor and limit idle time for the entire fleet.

As an established company we maintain professional integrity and accountability throughout every project. It’s the unity of our staff and our dedication to customer satisfaction that sets us apart from other companies in the industry. We are a certified, bonded and insured organization with rigid policy for Health and Safety.

Over the years, we have taken an active role in supporting the development and professionalism within the industry through participation with Landscape Ontario Horticultural Trades Association (LOHTA). We are also proud members of the Canadian Nursery Landscape Association, Canadian Green Building association (CGBA) and Technical Safety Standards Association (TSSA) and the Ministry of Environment (MOE).

Cornerstone is also involved with the communities by supporting major events and various charities throughout the year.
